Step 2: Historical Context.
It was constructed during World War II as an emergency measure to transport oil safely across the continent, avoiding the risk of tanker ships being attacked by submarines along the Atlantic coast.
Step 3: Significance.
It remains a vital part of the energy infrastructure in the United States, connecting the production centers in the south to the consumption centers in the north.
